A close friend of Claudia Lawrence says she always believed there would be progress in the case.
"I have always put my faith in the police," Suzy Cooper said. "I never really doubted that."
The 49-year-old, who lives in York and works in accounting, said it had been impossible for her to move on in her life after her friend's disappearance.
Over the last five years there have not been major things happening in Claudia's case. For five years that has been really frustrating. It feels more tangible now there is an arrest. I have been trying to focus on my own life but Claudia has always been in my thoughts. I have been told by zillions of people 'you have to get on with your life', but I haven't done it very well. I haven't been able to let go. I cannot put it to bed, I cannot say 'that's happened, move on' because it's still happening.
